Be it known that I, J. V. IVEITZ, of Cleveland, inthe county of Cuyahoga, and State of Ohio, have invented certain new and useful improvements in Steam-Engine Regulators; and I do hereby declare that the following is a full and complete description of the construction and operation el' the saine, reference being had to the accompanying drawings, making -apart of this specification, in which- Figure 1 is aifx'ont view of the regulator as attached to the steam valve. Figure 2 is a View of the steam valve, showing the induction port of the valve. Figure 3 is a view of the same, showingthe exhaust ports of ythe valve. Figure 4 is a section of the steam chamber, showing the induction ports ofthe chamber. Figure 5 is a longitudinal sectionalview of the valve and chamber. Figure 6, a transverse view ofthe saine. Figure 7, a vertical section of the regulator. Like letters of reference refer to like parts in the several views.. v A, fig. 1, is the steam chamber. B B are the steam ports. C C the steam throats, leading from the chamber to the cylinder, and upon which the valve and regulator stand. D is the induction steam pipe. E the exhaust steam pipe. F is the steam valve, and consists of a hollow cylinder, through the centre of which passes the rock-shaft G', iig. 5. At the lower side of this valve is the steam port Il, figs. 2. and 6. On the upper side is the exhaust port I, figs. 3 and .I J is a countcrbalance to the weight of the steam port II. a a is a packing which is let in to the face ci' the ecunterbalance, and is forced outward against the inner surface of the cylinder by the pressure oi' the steam which is admitted to the under side of the packing through holes provided for that purpose, and which are indicated by the dotted lines b b, iig. 5; these ports and packingmay be in a circular form if thought desirable. The face 4of the port II is also provided with a packing, arranged and operated in the same manner; by this means the valve is at all times kept steam-tight within the chamber, and equally balanced. K K are also' steam ports. The section of the chamber occupied by these ports is divided o' from the rest of the chamber by a diaphragm, L, tig. This diaphragm tits closely around the valve, thereby making a separate chamber, A, around the ports K and the end of the valve, in which the ports are. The rock-shaft Gr projects through the front end 'of the chamber, as shown in iig. 5, to the extreme end of which is connected the leverw. M M are two independent levers, their upper ends being connected together and placed upon the end of the projecting arm N, and from which they swing or vibrate. The lever M passes up between the levers M M, and is connected to them by the shaft c, upon which are the friction-rollers, cl, c,f, which work respectively in the slots of the levers M M", and by means of which the friction of working the lever is reduced and operates more easily and independently in'worlcing the steam valve for the purpose of receiving and exhausting steam into and from the cylinder, which is effected in the following manner: The position of thcvalve, as shown in tig. 6, shuts off the steam from the cylinder. On moving the valve, by means of the eccentric to which the valve is attached by means of the lever M', to the right, steam is admitted to the cylinder ,through the port H, first taking steam from the steam pipe D into the valvc'ports K, thence through the port II into the cylinder through the steam throatJ C; then by the reaction of the valve the steam freely exhausts, through the throat C, the portIB, into the chamber, thence through the port I into the exhaust E, and so on alternately, as the eccentric continues to oscillate the valve from right to left and from left to right. In order to give the engine a regular and uniform volume of steam, a governing apparatus is attached to the valve, and operated conjointly with it. This apparatus consists of a pair of balls, A A', iig. 1, connected to a ross-head, B, by the arms C C', and is suspended in a frame D and placed immediately over the levers on the rocleshaft, and to which it is connected by the stem or rod a, figs. 1 and 7. This rod connects with the levers by the intervention of the stirrup E', the lower ,end of the stirrup being secured to the shaft 0,-upon f which are the friction-rollers cl, e, f, while the upper end is pivoted to the lower end of the rod; the lower end of this rod or stem is provided with a thread which screws into a sleeve, F. On the lower end of the sleeve is a hand-wheel, G', for the purpose of screwing the rod upward and downward inthe sleeve for o purpose hereafter shown. This sleeve and rod are fitted to another sleeveII, in which it freely plays upward and downward, as the case may be. To the upper end of the sleeve I'I is. secured the cross-head I, t0 which the upper ends of the links J' are attached, the lower end being-eonnected to the balls A. The cross-head K' passes transversely through the sleeve I-I', slots in the sides of the sleeve being provided for that purpose. A holein the centre ofthe head permits ofthe rod or stem a' to pass up through it. 'Io this cross-head is pivotcd the lower end of the links Il', and the upper end to the arms C". 'lhe action of the regulator upon the valve is as follows: When the balls are down, as shown inl iig.L 1, the greatest ,degree oi' oscillation is given to the valve for the reason that the friction-rollers are now at the lower end of the slot in the lever M'. The vibration ofthe lever being greater as the distance increases from the centre of motion of the lever M', it follows that a greater vibratory action is thereby given to the lever M, which, as a consequence, gives the greatest degree of oscillation to the valve,'as above stated; hence the engine at this time is taking the largest or a. full head of steam. The accelerated speed of the engine causes the balls to expand, which lifts the rod a', to which the stirrup and rollers are attached, by means of the cross-head K', through which, as above stated, the rod passes. A collar on the rod, which rests upon the upper side of the head, allows the lifting of the rod by the cross-head, at the same time Vpermits it to slide freely through it. It is obvious that this lifting of the rod brings the rollers nearer the centre of the vibration of the lever M', hence the oscillation of the steam valve is cheeked and the steam proportionately shut off, and so on alternately as the balls may rise or fall, opening o1' closing the valvel lnore or less. In case any accident should occur to the regulator, as the slipping or breaking of the belt, so that the balls would in consequence fall and thereby open the steam `valve, causing the engine to' take on an undue head of steam, the governing apparatus is so arranged as to shut oif the steam, and in such an event cause the engine to stop. This is accomplished as follows: The sleeve II', as above stated, being connected to the cross-head I', is raised up on the falling of the balls; the sleeve F', being within the sleeve II', is raised up with it at the same time, by means of the collar on the end ol' the sleeve F', and a shoulder on the inside ofthe sleeve H', upon which t-he collar rests when being lifted. It ywill be observed that on screwing the sleeve F' down by means of the hand-wheel, G', so that the collar will be close to the shoulder within the sleeve II', the sleeve, and so also the stem, will be raised up the distance the cross-head I' slides upward on the rod, which will be sufficient to entirely shut of( the steam, and thercbystop the engine. On screwing the sleeve up, making a distance, more or less, between the collar and shoulder, the distance that the sleeve will thus be ruiscd will be less than the space between the shoulder and collar, for the shoulder will have to pass over the space `thus lmade to react the collar in order to lift it; therefore the valve will not be entirely closed, as in the former ease.

It will be seen that the sleeve may be screwed up so far as to be out of the reach of the sleeve H', which may be done in the4 ordinary working of the engine, but in this way it does not act as a guard against casualties above named. For the security of the engine, in the event of accident to the regulating apparatus,`the sleeve F' must be screwed down to or near the shoulder, so that the collar above described may be reached by it, and thereby raised up so as to shut olf the steam. 'lhese two actions of the regulator are entirely independent of each other; that is, the balls and eross'head, K', in connection with the rod a', for the purpose of gauging the amount of steam into the eylinder,'are not in any way affected by the operation ofthe sleeve and screw for the purpose above explained, notwithstanding they act conjointly and within each other.

By this arrangement of the governing apparatus I dispense with the use of thc throated valve in the following way: When it is required to stop the engine, the sleeve F' is screwed down bythe hand-wheel G', this, as above stated, raises the rollers, and thereby shuts off the steam by the lifting lof the rod a' by thc screw-sleevc F' and sleeve H', in the manner asabove described; and so, in order to start the engine, the sleeve is screwed up, thereby opening the valve or allowing it to be opened by. removing the collar up away from the shoulder, for When the wheel is screwed down the rod and rollers are lifted by the descent of the balls and the steam in consequence shut off.

What I claim as my improvement, and desire to secure by Letters Patent, is

1. The tubular shaft H", stem or rod c', in combination with the screw-sleeve F', links J', cross-head I', arranged in the manner andfor the purpose as described.

2. The steam-balance valve F', ports J, II, and K, as arranged in combination with the chamber A, and auxiliary chamber A", for the purpose and in the manner set forth.
